VALVE MOVEMENT.

Application ledJ'une 9,

My invention relates to valve movements and refers particularly to valvemovements junction with engines loperated byiinternal explosions, andwhich do away with puppet valves and the intricate and delicatemechanisms necessary in the employment of direct seating valves. j p fBecause of the rapid movement and repeated impact torce accompanying,theA use or" direct seating valves, they are subjected to great wear,become looserand noisy, do not produce positive closureA andare thecause ot great loss of power andot injury to the engine itself. j

Attempts to replace' valves of the character last described by revolvingsleeve valves, or longitudinally movable sleeve valves :have not-beengenerally successful because of the long and rapid mov-ement ot thevalve parts necessary for the most satisfactory results, causing a wearupon the valve elements and a breaking down of the movement-causingelements. j

The device ot my invention overcomes all of the above mentioned, andother objectionable features of valve movements, and presentsV anoscillating cylindrical valve, in which the relative movements of thecylindrical elements are annularly oscillating and ot' a minimum ofdistance movement.

In the device ot my invention, a plurality ot cylindrical elements,having properly positioned ports, oscillate in unison or in oppositionto each other, thus causing ,but a slight movement ot any particularvalve element. This results in a minimum of wear upon the moving ports,allows of rapid opening and closing of ports with a minimum of movementand produces a positive, non-leak` innl valve of the highest eiciency.

ll'n my device, Iemploy a plurality of cyliudr'cal valve members,preferably two, each having a plurality of ports, preferably four.oscillatable within and upon each other and within and upon a portedenclosure in the engine head, the several elements being so arranged andpositioned that only a very slight oscillating movement is necessary inorder to open and close the d-esired ports for the production of therequired engine operation.

Thevparticular form of the device of my invention Ishown intheaccompanying drawings comprises a combustion engine body 10,

having a'combustion chamber 11, and a plurality of connected watercooling chambers 12, 12, 12. Fixedly attached to the bony l0 is a headl,having the ports, or openings, 14 and 15 tor the entrance ot explosivegases, the ports or openings, 16 and 17 tor the exi. ot exhaust gasesand a passageway for the sparlrplug 19.v The head 13 also'contains aseries ot connected water cooling chambers 20, 20. Thev head has aVhorizontal cylindrical bore 21', connected -with the ports 14` 15, 16and 17. y

` Vithin the lbore 21, abutting upon the inner face thereof andrevoluble` therein..v is an outer hollow cylindrical valve member 22,having the ports or openings 23, Q4, 25 and 26; I prefer to have thisoutercylindrical valve member 22 inthe 'form of-a' split cylinder. 27,in order that compensation may be made torthe expansion due to the heatet process. 4lithiuthe outer Valvemember .22, abutting upon the innertace thereorn and oscillatable therein is an inner hollow cylindricalvalve member 28, split at 29 and havi the ports, or openings, 30, 31,32and 1Within the inner valve member 28, and fixedly attached thereto isa bracing or supporting member 84 l'iaving` the water cooling conduitrlhe outer and the inner valve members 22 and 28 carry packing rings 36,36, 36.

F or purposes ci rigidity and better wearing properties. l prefer tomake the lower portion of the inner valve member 28, that is the portionagainst which the explosion impact is exerted,somewhat thicker than theotherportions thereof;

The mechanism tor .oscillating the two cylindrical valve members 2 2and28 is as ich lows1 The sleeve 37 is integral with the outer valvemember 22, is iixedly attached to the arm v3.8, which is pivctallyattached to the link 39 at 40, the link 39 being pivotally at* tached tothe arm 41 at 42, the arm 41 being pivotally attached to the head 13 at43. The arm 41 carries a roller 44 wnich runs within a cam groove 45 ofa cam 46.

The sleeve 47, integral with the inner valve member 28, is fixedlyattached at the arm 48, which is pivotally attached to the link 49 at50, the link 49 being pivotally attache-d to the arm 51 at 52, the arm51 being pivotally attached to the head 13 at 53. The arm 51 carries aroller 54 which runs within a cam groove 55 ot a cam 56.

The two cams 46 and 56 are tixedly attached tothe shaft 57 carried bythe supporting arm 58. The cam shaft 57 carries the helical gear 59meshing with the helical gear 60 ot the shaft 61, the other helical ear62 of which meshes with the helical gear 63 of the power shaft 64.

The revolution ot' the power shaft 64, therefore, revolves the cam.shaft 57 thus oscillating the arm-link systems and oscilla-ting the twocylindrical valve members 22 and 28.

The relation of these inter-operative oscillating elements is such as toproduce the following movements in the several elements.

Figure 6 .shows the device in position for gas intake, the relativepositions of the ends of the arms 38 and 48 being indicated,graphically, by dot-anddash lines. The exit port 17 is closed and theexplosive gas is ldrawn into the explosion chamber 11 through the ports14, 23, 30, 31 and 24 in the direction of the arrow.

Figure 7 shows the device in the next position, that is the compressionor explosion phase, in which both' the ports 17 and 15 are closed, thearms 38 and 48 having been moved by the clamsto the position indicated.

Figure 8 shows the device in the exhaust `position, with .the port 1 5closed and the exhaust gases escaping in the direction of steps oiloperation.

the arrow through the ports 17, 25, 32, 33, 26 and 16. kThe arms 38 and48 having taken the positions indicated. The arms then return to thepositions indicated in Figure 6 for a repetition of the A considerationof the movements shown in Figures 6, 7 and 8, which covers aV full.cycle of power movement, .shows that in order to pass from intakeposition to compression position the arm 38 remains stationary and thearm 48 moves the short distance from its first position to agreementwith the arm 38. i position to exhaust position, the arm'48 remainsstationary and the arm 38 moves the short Adistance to the positionformerly occupied by the arm 48,- and to pass from exhaust position tointake position, the Vtwo arms 38 and 48 move the short distance toreverse position.

lt is to be particularly noted, therefore, that the, distance 4oi:movement of the arms 38 and 48 is very short, thus allowing ot eectiveopening and closing of the several conduits necessary in operationby'means ot' short element movements thus increasing the eliiciency ofthe device and reducing the absorption of power for operation to aminimum. It also reduces the throw of the parts, thus preventingexcessive wear and tear upon the moving parts.

For purposes of water cooling the head, water is introduced through theintake opening 65 and escapes through the outletopening 66 after havingpassed through the chambers 20, 20, 2l) and 35, as indicated.

The means adopted for internally cooling the member 34, which mightotherwise become overheated during the exhaust period, is shownparticularly in Figure 5, in which a pipe 67 is threaded to the member34 and revolves therewith. 1n order to form a supporting and water tightjoint between the revoluble pipe 67 and the stationary pipe 68, Ivemploy the jointure members 69 and 70 threaded in attachment andcarrying the revoluble ball 71, through which the pipe 67 passes and towhich it is lixedly attached. The water enters in the direction ot thearrow and passes through t-he pipes 67 and 68, the latter entering thevgeneral cooling system near the exit 66.

Proper means may be employed for lubrication of the moving parts. eCarbon receiving receptacles 72, 72, V72 may be recessed within theouter face of the valve member 22 if desired.
